This is kind of a two part question.I have a 95 Ford t-bird lx that has 85k on it and recently it has been chugging a little when i get to accelerating around 40mph and at about 1500rpm it just kind of dangles there and dosnt want to go any faster than that unless i really press the pedal to the floor. This being my first question about why this would be happening. My 2nd is where are my spark plugs located under my hood so that I can check to make sure i dont have a dead plug. Thanks!
